tModcl.)

1'0 all whom it may concern:

Be it known that 1, WILLIAM BROWN, of Duncannon, in the county of Perry, and in the State of Pennsylvania, have invented certain new and useful Improvements in Lightning- Uondnctors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements in lightning-rods; and it has for its object to furnish a better and more perfect conductor of electricity than has heretofore been obtained. This object I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents an elevation of my improved oonductor with a portion broken away, showing the interior thereof. Fig. 2 represents a view showing my improved conductor applied to a building, and Fig. 3 represents a transverse section of my improved conductor on the line .10 00 of Fig. 1.

The letter A indicates the main portion of my improved conductor, which consists of a hollow tube, preferably of a spirally-lapped strip of metal, as indicated in the lower portion of Fig.1 of the drawings. Within the tubular portion of the main portion of the con- ,ductor islocated aconvolute, B, of sheet metal, which may be made in sections of suitable length. The upper section extends upward beyond the main portion of the conductor, and is provided with a funnelshaped top, 0, preferably of copper. The said funnel serves a double purpose of attracting the lightning and conveying water to the spaces between the thus obtain the combined conductive capacity of a body of water and metal. The said funnel may have a plain edge or may be serrated, as indicated, for ornamentation.

The letter D indicates a metallic point surmounting the rod, which serves to draw off the fluid from a cloud, or from the atmosphere, in the usual manner. I

The upper end of the body of the conductor terminates in a funnel, E, which also serves to collect and fill the conductor with water. The part Bis placed within the rod A, so that any water collecting in the funnel attached to the rod will pass into the latter.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In combination with the tubular body of the rod, the interior scroll, constructed and arranged as and for the purposes specified.

2. In combination with the tubular body and the interior scroll, the funnel located on the body, substantially as specified.

3. In combination with the body of the conductor and interior scroll, the point secured to the upper end of the scroll, substantially as set forth.

4. The combination, with the tubular body convolute, so as to till the same with water, and 4e having a funnel at is upper end, of the inclosed scroll having a funnel and point at the top, substantially as and for the purposes specified.

In testimony whereof Iaffix my signature, in

presence of two witnesses, this 20th day of June, 1882.

WILLIAM BROWN.
